I. INTRODUCTION
Recently, ghost imaging (GI) has become a hot topic in
quantum optics [1]. Ghost imaging offers great potential,
with respect to standard imaging, for imaging objects in
optically harsh or noisy environments. The earliest GI
experiment was achieved on the basis of entangled photon
pairs. The theory of entangled photon pairs was proposed
by Klyshko [2]. Subsequent experiments and theories proved
that an entangled light source is not an essential condition
for GI; a classical, thermal light source also can realize GI
[3]. Subsequently, GI based on a thermal light source has
promoted many new studies, and has gradually progressed
from theory to experiment and practical application. Paper
[4] studied the applications of GI based on a thermal light
source, and the influence of noise on GI. Paper [5] improved
the imaging principle and imaging device of GI based on
a thermal light source. Paper [6] used a real thermal light
field to realize GI without an optical lens. In addition, Paper
[7] studied high-order GI and pure-phase-object GI. Paper
[8] combined an information-theory method with GI. In the
experimental aspect, second-order GI of a scattering medium
was successfully conducted in paper [9]. Paper [10] used
only one detector to achieve a successful experiment on GI
based on a pseudothermal light source. Paper [11] proposed
computational ghost imaging, reduced the complexity of the
experiment and improved its efficiency. Paper [12] improved
the algorithm for second-order GI and proposed differential
ghost imaging.
A rosette scanning seeker is a type of single infrared
(IR) detector [13]. A rosette scanning system uses a fixed
instantaneous field of view (IFOV) to scan the total field
of view (TFOV), detects the target location and image
information, and then restores the detected information
through a variety of processing methods. It has important
application value and is a low-cost infrared homing tech-
nology. Paper [14] proposed a method to design a small
IFOV without lessening the TFOV, to solve the problem that
the previous method could not achieve full scan coverage,
but accurate imaging of objects in a harsh environment
was still a question. In paper [15], the information from a
single-detector rosette scanning system was used with
compressive sensing to reconstruct the image, and work
efficiency was improved. However, as a receiving device,
the detector is easily influenced by the light source, and
other factors. In this paper we propose a scheme for ghost
imaging based on rosette scanning, named rosette ghost
imaging (RGI). RGI combines ghost imaging and a rosette

Ghost imaging offers great potential, with respect to standard imaging, for imaging objects in optically
harsh or noisy environments. It can solve the problems that are difficult to solve by conventional imaging
techniques. Recently, it has become a hot topic in quantum optics. In this paper, we propose a scheme
for ghost imaging based on rosette scanning, named rosette ghost imaging. Sampling a small area sampling
instead of the whole object, the instantaneous field of view of rosette scanning is used as the modulation
light field in ghost imaging. This scheme reduces energy loss, the number of samples, and the sampling
time, while improving the quality of the reconstructed image.
